Collision Avoidance Using Communication between Autonomous Mobile Robots

摘要

This paper addresses mutual collision avoidance between multiple mobile robots based on a layered strategy. In this Strategy, static motion generation and dynamic motion generation of several levels are provided , and a proper level of dynamic motion generation is selected for mutual collision avoidance according to the complexity of the situation. We have implemented two typical methods in the layered strategy , which are rules-based local collision avoidance and negotiation-based global one using communication. In each method, a robot detects collision and applies as a local method as possible. Experimental results show two actual mobile robots can achieve mutual collision avoidance based on the layered strategy.
